A radical option - but one that isn't feasible for any kidney patient - is to take a one of those bowel pre-operative prep solutions (they come in enema format & can clean everything out within 2-5 minutes apparently). But it is contraindicated in renal impairment as well as those taking calcium channel blockers. Sodlum, phosphate & calcium electrolyte levels can be severely affected by this dangerous substance.
It's hard to imagine how peoplel manage when they have problems. There must be a solution. I firmly Believe that all plants are on this planet for our use. We have simply forgotten what and how each one can be used for. Diet is critical to body function, but what works well for one may not work at all for another. We do have individual needs. It can be tough finding what works for you.Then again, there is a whole lot of truth in bacterial treatment. Gut bacteria is an intense education yet to be researched and learned. Many people can benefit from this and sad to say, this is going to take many years before it becomes anything like a normal medical practice.
